      Entry Details

      PCGS Number: 83716
      Coin Date: 1866
      Denomination (Short): 3cS
      Denomination (Long): 3-Cent Silver
      Desg: PR
      Composition: 0.9 silver; 0.1 copper
      Mintage: 725
      Strike Type: Proof
      Coinage Type: Three cent silver
      Coinage Years: 1859-1873
      Mint Location: Philadelphia
      Diameter: 14
      Fineness: 0.9
      Weight (Grams): 0.75
      Weight (Ounces): 0.02646
      Designer: James B. Longacre
      Edge: Plain
      Obverse Description: A six-pointed star with a harp in the center is surrounded by UNITED STATES OF AMERICA on the periphery and the date positioned at the bottom. For the type III issues (1859-73) there is a single frame line around the star.
      Reverse Description: The roman numeral III is centered in the design ensconced in a large, bejeweled letter C surrounded by 13 stars on the periphery. An olive sprig is added above the roman numerals.
      General Notes: The 1866 Proof Three Cent Silver comes from a moderately low mintage for its series of 725 coins; most of which were saved leaving the issue readily available to collectors and relatively affordable. Scarce only in gem condition. Cameo pieces are far more difficult to locate in all grades and deep cameos are a rarity. Look for attractive toners as this series is full of them.
